Thanks Ammu!
So now it's confirmed Suraj is the one going on the mission and not Chakor. It's a relieve to know Suraj's real/fake marriage is probably part of the mission and isn't doing it because of reasons like assuming Chakor is dead, forced by Teju, Bhuka or in anger because she left him etc.
As Mesh said both of the tracks will probably be running in parallel Suraj on this mission and Ragini vs Chakor-Vivaan-Imli. I find this new track with Suraj going on the mission interesting it has the potential to give us lots of beautiful Sukor scenes to cherish. Sukor yearning and longing for each other, secret meetings or phone conversations also maybe Chakor helping Suraj in some aspects of this mission where possible etc.
